i To all 'whom 'it concern:

Be it known that I, RICHARD-G. FONTANA, a citizen of the United'- States, residing in the city and county of San Francisco and State of California, have invented certain new andv useful Im rovements in Cherr Stemmers, of which t efollowing is a s eci cation. A My invention relates to t e class of fruitstemming machines. Its object is -to provide a simple, efficient and practical machine,

especially adapted for removing the stems y from cherries.

Myinvention consists generally, in a slotted trough or channel to receive and hold the cherries, the'stems of which .protrude through thel slot, and in suitable grippers,

preferably in the form of rotatable, adJacent rolls, disposed to seize the protruding stems, and pull them from the cherries.

` It also consists in the novel construction and Varrangement of the machine which I shall hereinafter fully describe, by reference to the accompan 4drawings in which Fgure 1 1 s a s1 e view, roken, of my machine. .2 V1s ,a crOss-sectlonal v1ew,

Y th, a slot 3, the width of permit `the stems of the cherries to protrude `throughit.

The table 1 is mounted in a suitable frame 4,`which is carried from a stand 6. On thez supports 5, the table is given a shal'n'n -reciprocating motion-in the directionof its e th.

At the .head or feed end ofthe table, is a I feeder board 7, provided with guide cleats 8,

of suitable character, adapted to direct the cherries to', the troughs 2'. .Any suitable mechanism maylbeem 1o ed to shake the p li, e here shown av 9\.secured to thd lis confor this p e, a be" shame.

verselyto its slot,

.113 are thest'em gripper rolls. These lie 'directl` under the' troughs 2, and are array e astraversing the plane of the slots 3 o the troughs, as shown. The rolls may be in any number, and they lie 4side by side, in close proximit to each other. They may be geared throug out, as shown at 14, in such manner that adJacent rolls rotate in opposite directions. They may be driven from the main shaft by a belt 15, as shown in Figstl 1 and 2 g and they may be made of any suitable material.

A suitable receptacle for the stemsl may be .provided below the rolls, and another receptacle, such as 16, for the cherries, may be disposed-at the` foot of the table.-

`The o eration of the machine is as follows e cherries aresu'pplied to the feed board 7, lon which, due to its shaking motion and its spring supports 5, the; spread out,

one layer thick, and advance own between the guide l`cleats 8, by which they are directed into the troughs 2. They fall 'singly and successivelyinto the troughs, in which, due to the Inclined walls and the shaking motion, they. seek the trough bottoms, turn` their stems downwardly and protrude themthrough the slots'3,and so advance, in single file, from the head to the foot. The protruding stems are cau which rotating,p the stemsfrom the resisting cherries, which cannot pass. through the slots; and while the stems are passed between the rolls and discharged, the stemmed cherries arevdelivered from the foot of the table into the receptacle 16.A
